Ill-2 a RESILIENT HEEL Application filed January 24, 1921.

To all "whom it may c012 cera:

Be it known that I, Thurman HENRY Qnannn, a citizen of the United States, temporarily residing in the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Resilient Heels, of which the following is a specification.

My invention relates to improvements in resilient heels, and relates more particularly to the class of heels known as rubber heels used on boots and shoes, and the object of my invention is to provide a heel of the class set forth made of two sections, one of which is designed to be permanently carried by the heel of the boot or shoe, and the other of which is designed to be replaced as it wears. Another object of the invention is to provide a composite heel with a central interior cavity whichwill provide more or less a cushion effect in the middle of the heel.

In the following specification I shall describe the essential features of my heel, and what I claim as new will be set forth in the claim forming part of this specification.

Fig. 1 is a side elevation of my composite heel. Figs. 2 and 3 are elevations of the inner side of each heel section, and Fig. r is a vertical central longitudinal section of the assembled members of my heel portions of the central part being broken away to facilitate illustration.

In the drawings, like characters of reference refer to the same parts.

A. is the upper or permanent member of my heel, and the same is provided in the usual manner with the holes B through which the fastening means is passed whereby the said member is attached to the heel of the boot or shoe (not shown). Formed substantially centrally of the member A, and in the underside thereof is an annular groove G. D. is the lower or removable member of the heel, and of course the same is substantially of the same shape as the member A. E. is an annular groove formed in upper side of the lower member D and this groove coincides with the groove 0. when the member D is placed over the member i: Of course, as is common in the art, the abutting surfaces of the members A and D are coated with any suitable cement so that when any suitable fastening means is passed Specification of Letters Fatent.

through the holes F formed in the member D, the said members will be held together and so permit of the cementing of the same together. A certain amount of air will be imprisoned in the annular chamber G- formed by the grooves C and E when the members A and D are placed together, and as this annular chamber is positioned substantially centrally of the heel a certain pneumatic effect will be had which will increase the resiliency of the heel. without in any way weakening the construction.

The fastening means passed through the holes F would of course pierce the member A and enter the heel of the boot or shoe (not shown) but in order to relieve the fastening means just mentioned of a portion of the lateral strain brought into effect when the lower member D is brought against the ground, I provide the lower member D with a stud H having preferably tapered sides,

which stud easily enters the tapered pocket I formed in the member A, when the said members are placed together. J. is a stud forming part of the member D and rojecting above the upper side thereof as does also the stud H), and the stud J is designed to easily enter the pocket K formed in the underside of the member A, when the said members are placed together. These studs and their respective pockets will also be coated with cement and will assist in keeping the members A and D firmly bound together.

When the lower member D is brought into contact with the ground or pavement the co-action between the studs H and J and their respective sockets will absorb a considerable portion of the strain that would otherwise have to be solely taken care of by the fastening means held in the holes F.

It will be understood that in case the lower member D be knocked away that the upper member A. may be used alone as a resilient heel, and the annular groove A. and the pocket I will very materially increase the frictional contact between the member A and the roadway or pavement. Various changes in construction may be made in the designs shown in the drawings without going outside the scope of my claim.

One great advantage flowing from my invention resides in the fact that the mem- Feared to the other boot.

ber D can be interchanged with a like memher, when, Wear occurs so that an unworn portion of the member D will be ready for use: in other words if the lower member D on the right boot is worn, it can be removed and interchanged with the member D se- This fact very considerably lengthens the life of this class of heel.

Although I mention that the two men bers A and D may be cemented together, this is not essential. While I prefer to make the members A and D with the grooves G and E, it. must be understood that I may omit these grooves, and use the studs I and J and their assoelated sockets, alone, since the heel elements so constructed are interchangeable.

What I claim is: Y

As a new article of manufacture, a rubber heel comprising con'iplementally formed upper and lower lifts, the lower face of the upper liit having an annular groove therein and a socket arranged centrally of the groove defining an annular shoulder in wardly of the groove and surrounding the socket, the upper face of the lower lift having an annular groove formed therein registering with the aforesaid groove, and a stud projection centrally of the lower lift adapted to be receivedin the aforesaid socket.
